NAILING GROUND STUDDING Filed June 20, 1939 3mm WGHurZBerZ; J22,

Patented Oct. 15, 1940 a. UNITED STATES PATENT ori ice This inventionrelates to steel building construction, and more particularly to animprovement in studding of type known as four-angle studs which are soconstructed as to permit of receiving nails or other fasteningsthroughout the full length of the stud.

To that end, the invention contemplates novel means for connecting thepairs of angles constituting the opposite chord members of the stud, in

such a way that the juxtaposed faces of the angles are yieldingly heldin assembled position. More specifically, the present invention providesnovel web members for connecting the chord angles in such a way that theangles may readily l5 spread apart upon the insertion of a drivenfastening and yet grip the fastening tenaciously without distorting theangles forming the chords in any way to impair their strength orefficiency in the ultimate wall construction.

20 With the above and other objects in view, which will more readilyappear as the nature of the invention is more readily understood, thesame consists, in the novel construction, combination I and arrangementof parts hereinafter more fully 25 described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in theaccompanying drawing, in which:

Figure l is a perspective view of the embodied 30 stud.

Figure 2 is a detail perspective view of a portion of the stud shown inFigure 1.

Similar reference characters designate corresponding parts, throughoutthe several figures 35 of the drawing.

Rleferringto Figure 1, it will be observed that the stud designatedgenerally as A includes the opposite'chord member's B, each consistingof a pair of angle members l--i. These angle mem- 40 bers have theirinwardly directed flanges connected by the transverse web elements C.

The said web elements or cross pieces C preferably consist of the strapor strip elements 22 which are of duplicate formation. Said members 2-2are so formed or bent as to have their medial portions 3 in contact andsecured together by any suitable fastening means, such for example, asspot welds. The outer ends 4 of each 50 member are offset relative tothe plane of the medial contacting portions 3, so that each web memberor cross piece in effect becomes provided with a forked or U-'-shapedend. when the members #4 are assembled. The saidends I are each 55 spotwelded or otherwise secured to the outer faces of the inwardlyprojecting flanges of the angles l-l which form the chord members 3.

It will thus be apparent that the adjacent faces of the inwardlyprojecting flanges of the angles ll held in substantial contact, but due5 to the yielding characteristics of the portions 4-4 of the members 2-2constituting each web element, the said angle members i-i areresiliently supported so that they can be sprung apart when a fastening!is forced in the slot between 10 the angles.

It has been heretofore customary in making a stud construction 'ofthistype to utilize a single web member or cross piece secured between theadjacent faces of the inwardly projecting flanges of ,the chord angles.However, this construction is open to the objection that the spacebetween the angles is blocked at intervals where the web members aresecured therebetween. Thus, it is impossible to drive a fasteningbetween the chord members at the location of the web elements in thisform of construction. However, on the contrary, with the presentconstruction, where the web elements are secured to the outer faces ofthe inwardly projecting flanges of the angles forming the chord members,it will be observed that a continuous nailing slot is providedthroughout the length of the stud. In other words, no obstruction isoffered to a driven fastening anywhere along the face of the stud, whileat the same time the chord angles are firmly held in properly assembledrelation to issue a tenacious grip with the shank of the fastening whichis forced between the chord angles.

From the foregoing, it will be apparent that by deforming the medialportions of the web' elements or cross pieces relative to the ends andwelding the medial portions together, while the ends carry the angles, aline contact is provided not only between the angles for receiving 40 afastening, but, the fastening may also be driven into the zone of theends-of the web members. This result is possible because thesubstantially bifurcated or'U-shaped formation at the ends of the webmembers, previously described, extends a substantial distance inwardfrom the inwardly projecting flanges of the angles constituting thechord members.

Without further description it is thought that the features andadvantages of the invention will be readily apparent to those skilled inthe art, and it will, of course, be understood that changes in the form,proportion and minor details of construction may be resorted to, withoutdeparting from the spirit of the invention and scope of the appendedclaim.

I claim:

A nailing ground stud, comprising, opposite chords consisting of anglemembers arranged back to back whereby their inwardly directed flangesprovide nail gripping faces of extended depth, and means connecting theouter faces of said angles to provide a continuous nailing slotthroughout the length of each chord, said means including, web elementsconsisting of a pair of metal strips each having their outer endsoppositely offset from the plane of the strip whereby when the stripsare placed together, their medial portions will be in contact and saidouter ends will be spaced apart to provide spring jaws for engaging theouter races of the said inwardly directed flanges of the angle membersto enable 5 the same to resist spreading under nail pressure,

means securing the contacting medial portions of the web stripstogether, and means securing the outer ends of the stripsito the saidouter faces of the inwardly directed flanges of the angle 10 members.
